Ratio of molar heat capacity at constant pressure and at constant volume for monoatomic and diatomic gas is?
25 : 21
21 : 25
16 : 25
25 : 16
The Correct Option is A
Solution and Explanation
The correct answer is(A): 25 : 21
\(\frac{5}{3}\)/\(\frac{7}{5}\) \(\Rightarrow\)\(\frac{5}{3}\)x\(\frac{7}{5}\) = \(\frac{25}{21}\)

Concepts Used:
Specific Heat Capacity
Specific heat of a solid or liquid is the amount of heat that raises the temperature of a unit mass of the solid through 1°C.
Molar Specific Heat:
The Molar specific heat of a solid or liquid of a material is the heat that you provide to raise the temperature of one mole of solid or liquid through 1K or 1°C.
Specific Heat at Constant Pressure or Volume:
The volume of solid remains constant when heated through a small range of temperature. This is known as specific heat at a constant volume. It is denoted as CV.
The pressure of solid remains constant when heated through a small range of temperature. This is known as specific heat at constant pressure which can be denoted as CP.
